UltraPower upgrade. I installed the upgrade in March. I didn't get good results at first and contacted them. 1200 miles was suggested to "break it in". I have 1600 miles on it now and my mileage is worse. Also, the power climbing hills is less. I was better off before the upgrade. Plug wires were checked OK and fuel filter OK. Anyone else have this problem?
